BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of audio file transfers and,more particularly, relates to the field of management and distributionof audio files over a computer network such as the Internet.

2. Description of the Related Art

The Internet is a worldwide array of interconnected computers andinformation servers that allow anyone with a computer and access to theInternet to get information about virtually any subject 24 hours a day.For the average consumer, an Internet Service Provider (ISP) providesaccess to the Internet. ISPs such as CompuServe, Prodigy, and AmericaOn-Line, currently link over ten million users to the Internet. Userstypically connect to the ISP by using standard telephone lines and atelephone modem. Cable modems that allow a user to connect to the ISPover cable television lines, and satellite connections to the Internet,are also available.

The Internet provides a wealth of information from stock reports toheadline news. One of the newer services provided on the Internet is astreaming audio (e.g., RealAudio and MPEG audio) service. Streamingaudio services are often provided in connection with the World Wide Web(Web) and thus are often called Web radio broadcasts. With streamingaudio, a user with a Personal Computer (PC), a sound card, and thenecessary software can listen to audio programs from anywhere in theworld. For example, Radio Prague provides daily Internet broadcasts fromthe Czech Republic. Listeners in the U.S. can listen to these Web radiobroadcasts either in real time, or stored for later replay. Thus, unlikemore traditional radio broadcasts where the listener must be within areception area, Web radio broadcasts can be heard anywhere, so long asthe listener has a connection to the Internet and the necessary computerhardware and software.

Unfortunately, even with the ever-decreasing cost of personal computers,the hardware and software needed to listen to a Web radio broadcast isbeyond the financial means of many people. Even for those that canafford a personal computer, listening to a Web radio broadcast ties upthe computer so that the user cannot use it for other purposes.Moreover, the use of a personal computer to receive streaming audio(e.g., Web radio broadcasts) requires a certain amount of computerliteracy on the part of the user. The user must be able to install theWeb Radio software, configure the Web Radio software to communicate withthe ISP, and find the various Web radio broadcasts provided on the Web.

In addition to listening to Web radio broadcasts, users may wish tolisten to audio files. With a group of PC's in a home and in a network,users can download songs from one PC to another or upload songs from onePC to another. However, users cannot play a song on one PC by using thecontrols of another PC. In addition, the users must purchase multiplePC's, which can be costly. Further, the user must be able to install thenetwork connection and the appropriate software. Moreover, even if theuser can afford to purchase multiple PC's and install the properconnection, the user would have difficulty playing music in addition toperforming other tasks on the PC. For example, the Web radio broadcastmay be interrupted. Also, a skip over parts of a song may result if theuser is using a word processing program at the same time as listening tomusic.

SUMMARY OF THE INVENTION

The present invention solves these and other problems by providing anetwork-enabled audio device for listening to a variety of audio sourceswith substantially equal convenience. The network-enabled audio devicehas a visual display for providing audio source choices to a user. Thevisual display also provides functions for managing audio sources.

DETAILED DESCRIPTION

One aspect of the present invention is an intelligent radio device thatallows a user to receive digitized radio broadcasts over the World WideWeb (Web). The intelligent radio provides the hardware and softwarenecessary to receive digitized audio from the Web without the need for apersonal computer or other expensive equipment. The intelligent radioprovides a display device, such as a Liquid Crystal Display (LCD) thatallows the user to select a desired Web broadcast from a list ofavailable Web broadcasts. The display also allows the user to select Webbroadcasts in a particular language. The software, the user controls,and the display in the intelligent radio 100 are operably configured andconnected such that a user can tune into a Web radio broadcast in amanner similar to the way a user would use the controls on aconventional radio to tune into an AM or FM radio station. Thus, theintelligent radio provides people who are not comfortable withcomputers, or who do not own or have access to a computer, anopportunity to listen to streaming audio information from the Internet.

In one embodiment, the intelligent radio is a low-cost tabletop box thatconnects to an AC power line and a phone line. The device includes adisplay device, speakers, a control panel, a computer processor, astored software program, and a modem. The intelligent radio uses themodem to establish a telephone connection to an Internet ServiceProvider (ISP). The stored software program connects to a Web Radio homepage, via the ISP, and downloads a list of Web radio station addresses.Alternatively, the user can enter a web address (e.g., a UniformResource Locator (URL)) to connect directly to a web page that providesaudio broadcasts (instead of first connecting to the Web Radio homepage). The user may use buttons on the control panel to scroll throughthe display and select a Web radio broadcast “station” for listening.When a station is selected, the stored software program connects to thestation and begins to receive digitized audio data transmitted by thestation. The intelligent radio converts the received data to analogaudio and plays the audio on one or more loudspeakers.

In an alternate embodiment, the intelligent radio is a tuner thatconnects to an audio system such as a component stereo system. The tunerprovides an audio output to the audio system. The audio system providesamplifiers and loudspeakers. The tuner comprises an enclosure thatconnects to an AC power line, a network line, and the audio system. Thenetwork line may be any type of computer data connection, including, forexample, a telephone line, a cable line, an Ethernet line, a Token-Ringline, a twisted pair line, an infrared link, a radio frequency link, anIEEE-1394 FireWire line, etc. The tuner includes a display device, acontrol panel, a computer processor, a stored software program, and amodem. The intelligent radio uses the modem to establish a telephoneconnection to an Internet Service Provider (ISP). The stored softwareprogram connects to a Web Radio home page, usually provided by the ISP,and downloads a list of Web radio stations. A user uses use buttons onthe control panel (or remote control) to scroll through the display andselect a Web radio broadcast “station” for listening. Alternatively, theuser may use voice-activated commands to scroll through the display.When a station is selected, the stored software program connects to thestation and begins to receive digitized audio data transmitted by thestation. The intelligent radio converts the received data to analogaudio, which is provided to the audio system.

FIG. 1 illustrates one embodiment of a tabletop intelligent radio 100.The intelligent radio 100 is mounted in an enclosure 101 and connects tohousehold AC power through a power cord 104 and to a communicationsnetwork by a network cable 102. The network cable 102 may be a telephoneline, a network cable, a cable TV cable, a connection to a wireless(e.g., satellite) unit, etc. For example, the communications network mayuse Iridium satellites developed by the Motorola Corp., Globalstarsatellites developed by a consortium of European manufacturers whichincludes Aérospatiale and Alcatel, P21 satellites developed on a projectfinanced by Inmarsat, or the Odyssey satellite system developed by a TRWconsortium associated with Teleglobe/Canada.

User controls are mounted on the front of the enclosure 101 and includea combined on-off and volume control 110, a command button 121, a cursorcontrol 116, a select button 118, a tuning control 114, and a button bar120. The cursor control 116 provides up, down, left, and right movementsof a cursor or other entity on a display device 112. The button bar 120provides buttons to select an audio source, including, for example, “AM”radio, “FM” radio, “Web” radio, “Cassette”, and “External” input. Alsomounted on the front of the enclosure 101 is the display device 112,which provides information to the user. An optional cassetteplayer/recorder 130 provides the capability to play and record audiocassettes. The intelligent radio 100 also includes a left stereo speaker106 and a right stereo speaker 108 that may be mounted in the enclosure101 or in separate enclosures. A wireless remote 135 provides remoteoperation of the intelligent radio 100. In some embodiments, amicrophone is provided as well. An output from the microphone isprovided to an analog-to-digital converter to convert the analogmicrophone signal into digital data. The microphone may be placed in theintelligent radio 100, in the wireless remote 135, or both.

FIG. 2 is a block diagram of the functional elements of the intelligentradio 100. The intelligent radio 100 comprises a Central Processor Unit(CPU) 202 that is used to run the intelligent radio software. The CPU202 is connected to a random access memory 204, a data storage device210, and a modem 206. The data storage device 210 may be any type ofnon-volatile data storage device, including, for example, a floppy diskdrive, a hard disk drive, a flash memory, a CD-ROM, a DVD-ROM, a CMOSmemory with battery backup, etc. The data storage device 210 providesstorage for software programs used by the intelligent radio 100. Thesoftware stored on the data storage device 210 may be upgraded bydownloading new software from the Web. The data storage device 210 mayalso provide storage for digitized audio material, such as recorded Webradio broadcasts, CD-Audio, etc. The modem 206 is connected to acommunications network 230, shown as a Public Switched Telephone Network(PSTN), by the network cable 102. Although the communications network230 is shown as a PSTN network, one skilled in the art will recognizethat the network 230 may also be a cable television (CATV) network, asatellite network, or any other communications network. In oneembodiment, the network 230 comprises both a Direct TV/PC satelliteconnection that provides information to the intelligent radio 100 athigh speed (e.g., 400,000 bytes per second or more), and a PSTN networkconnection so the intelligent radio can upload information back to theISP 232 (because many Direct TV/PC connections are only one-way). In yetanother embodiment, the satellite network is a two-way satellite networkthat uses the satellite for both download and upload. In one embodiment,the satellite network uses the Iridium™ system developed, in part, bythe Motorola Corp.

Optionally, a telephone 229 is connected to a first port of a codec 260.A second port of the codec 260 is provided to the CPU 202. The codec 260provides digital-to-analog conversion and analog-to-digital conversionfor the telephone 229. The codec 260 also provides standard telephoneinterface signals, such as a ringing signal, to the telephone 229, andtelephone status conditions, such as receiver up or receiver down, tothe CPU 202. In some embodiments, the codec 260 and the modem 206 may becombined as a telephone modem. The telephone 229 may be connected evenwhen the network 230 is not a telephone network.

The modem 206 provides an interface between the CPU 202 and thecommunications network 230 and the operational characteristics of themodem 206 are determined by the type of communications network 230.Thus, if the network 230 is a PSTN network, then a telephone modem isused; if the network 230 is a CATV network, then a cable modem is used,etc. In a preferred embodiment, the modem 206 is integral to theintelligent radio 100. In other embodiments, the modem 206 is providedin a separate enclosure. An Internet Service Provider (ISP) 232 providesthe user with a connection from the communications network 230 to theWeb via the Internet 234. Note that FIG. 2 shows functional elements,but not necessarily hardware configurations. Thus, for example, themodem 206 may be implemented in software on the CPU 202. The CPU 202 maybe a Digital Signal Processor (DSP). The CPU 202 may comprise a singlecomputer processor, or multiple computer processors. In one embodiment,the CPU 202 comprises two processors, a DSP and a general purposemicroprocessor. In one embodiment, the modem 206 is provided in aplug-in module such that the intelligent radio can be configured fordifferent types of computer networks by simply changing the modemplug-in to suit the type of network being used.

The CPU 202 provides data to the display device 112. The CPU 202receives user inputs from the command button 121, the tuning control114, the button bar 120, the select button 118, and the cursor control116. The CPU 202 provides digitized audio samples to an input of aDigital-to-Analog Converter (DAC) 220. The analog audio output of theDAC 220 is provided to an amplifier 222. In a preferred embodiment, theDAC 220 and the amplifier 222 are each two-channel devices, providingleft and right stereo channels. A left channel output of the amplifier222 is provided to the left channel speaker 106 and a right channeloutput of the amplifier 222 is provided to the right channel speaker108. The volume control 110 controls the gain of the amplifier 222.

As shown in the preferred embodiment in FIG. 2, the other optional audiosources such as the cassette device 130, an AM tuner 240, an FM tuner242, and an external input 244 also provide inputs to the amplifier 222.Other optional audio sources may be provided, such as, for example, anaudio CD, a DVD, a digital audio tape unit, etc. The CPU 202 controlsthe cassette device 130, the AM tuner 240, the FM tuner 242, and otheroptional audio sources. A line output from the amplifier 222 may also beprovided to a record input of the cassette device 130.

As described above, the button bar 120 is used to select one of theaudio sources. When the button bar 120 is set to “AM,” the intelligentradio 100 operates in an AM radio mode. In the AM radio mode, an analogoutput from the AM tuner 240 is provided to the amplifier 222.

FIG. 5 is a flowchart 500 that begins at a start block 501 andillustrates the Web Radio mode process. The process advances from thestart block 501 to a decision block 502, where the process checks astatus flag to determine whether or not the intelligent radio softwareneeds to be initialized (setup). If setup is needed, then the processadvances to a process block 504; otherwise, the process jumps over thesetup steps to a process block 514. In the process block 504, theprocess obtains a phone number for the desired ISP 232. The phone numbermay be obtained from a default phone number stored in the intelligentradio software, or by prompting the user through the data-entry display450. Once the phone number has been obtained, the process advances to aprocess block 506, where the modem 206 dials the telephone number andestablishes a modem connection with the ISP 232. Once the connection isestablished, the process advances to a process block 508 where the userestablishes an account with the ISP 232.

In one embodiment, the user is prompted for a password that is stored onthe data storage device 210 or entered using the data-entry display 450.Establishing an account may include other actions, such as creating ausername for the user, changing the phone number used to access the ISP232, and entering information about the user and the user's account.Once an account is established, the process advances to a process block510 where a list of available Web radio broadcast stations is downloadedto the intelligent radio 100 from the ISP 232 and stored on the storagedevice 210. Lists of available languages and program types are alsodownloaded and stored on the storage device 210. Once the lists aredownloaded, the process advances to a hang-up block 512 wherein themodem 206 terminates the network connection (e.g., hangs-up the phone).Upon hang-up, the setup process is complete, and the process advances tothe process block 514.

In the process block 514, the modem dials the ISP 232 and then advancesto a process block 516 where the intelligent radio 100 logs on to theuser's account at the ISP 232. The hang-up, redial, and logon (blocks512, 514, and 516, respectively) is desirable when using a PSTN, becausethe initial telephone call, placed in the block 506, is typically along-distance call or a toll-free (e.g., a 1-800) call. By contrast, thetelephone call placed in the block 514 is typically a local call. Whenusing a non-PSTN network (e.g., a cable modem, a satellite network,etc.) then the hang-up, redial, and logon (blocks 512, 514, and 516,respectively) is typically omitted.

Once the user is logged on, the process advances to a process block 518where the user selects (tunes) a Web radio broadcast station. Once a Webbroadcast has been selected, the process advances to a process block 520where the intelligent radio 100 receives the Web broadcast. The CPU 202decodes and decompresses the received data as necessary and then sendsthe decompressed data to the DAC 220 where it is converted to an analogsignal that is subsequently played on the speakers 106, 108. The processremains in the process block 520 while the user listens to the Webbroadcast.

If the user tunes to a new Web broadcast station (e.g., by turning thetuning control 114 or by activating the select-broadcast display 340)then the process loops back to the process block 518, selects the newstation, and returns to the process block 520.

FIG. 6A illustrates the information management and data processingfunctions 600 provided by a Web Radio site 602 (e.g., www.webradio.com).Access to the Internet site 602 is made possible by the Internet accessprovided by the ISP 232. The Internet site 602 provides a list of Webradio broadcast stations for the user and optionally other value-addedservices that enhance the operation of the intelligent radio 100. Forexample, the Internet site 602 may provide a list of available programsources and streaming audio programming. The site 602 may also maintainuser profile comprising a list of preferred Internet “broadcaststations.” The site 602 also provides special download capabilities suchthat the user can download information and software into the intelligentradio. The site 602 also provides upload capabilities such that the usercan upload information, such as preferences, etc., from the intelligentradio 100 to the site 602. For example, the site 602 can provide acustomized list of stations for each user and voicemail capability. Thesite 602 may provide reformatting of streaming audio data into a formatbetter suited for the intelligent radio.

In one embodiment, the site 602 also provides Web telephone capabilitiesto the intelligent radio 100, such that the user can use the intelligentradio as a telephone to talk to other users that are connected to theInternet. In one embodiment of the Web telephone, the codec 260 is usedto digitize speech from a microphone in the handset of the telephone229. The digitized speech is sent over the network 230 to the ISP. TheISP forwards the digitized speech to a remote user. Similarly, the ISPprovides digitized speech from the remote user to the intelligent radio.The intelligent radio uses the codec 260 to convert the digitized speechinto analog signals that are played on the speakers 106 and 108 or aspeaker in the handset of the telephone 229.

In yet another embodiment, the intelligent radio provides voice email inconnection with the site 602. To receive email, text-to-voice softwarein the site 602 is used to convert email text into digitized voice dataas words spoken in the user's desired language. The digitized voice datais provided to the intelligent radio where it is converted to an analogsignal and played on the speakers 106 and 108 or a speaker in thehandset of the telephone 229. To receive email, the user speaks into themicrophone 250 or the microphone in the handset of the telephone 229 andthe spoken words are converted into digitized speech by the intelligentradio. The intelligent radio sends the digitized speech to the site 602where it is converted into email text and then emailed to the recipient.The software to convert speech to text and text to speech is provided inthe site 602 in order to minimize the cost and complexity of theintelligent radio. Alternatively, the software to convert speech to textand text to speech is provided in the intelligent radio.

In one embodiment, the site 602 also provides special formatting andmarkup protocols that are tailored to the intelligent radio display 112.Most existing Internet sites are geared towards a computer or televisionand assume that a user has a large, high resolution, color monitor. Mostexisting Internet sites also assume that a user is accessing the site byusing a Web browser such as Netscape Navigator™ or Microsoft InternetExplorer™. These browsers support high level protocols such as HyperTextMarkup Language (HTML). The display 112 may be relatively smaller, andrelatively less capable than a traditional computer monitor. In someembodiments, the display 112 does not necessarily need all of thecapabilities and complexity of HTML and is thus better served byinformation that is formatted for the display 112 and that is expressedin a markup language that is suited to the needs of the intelligentradio 100, without the overhead and complexity of HTML.

When the user connects to the Internet site, information is passed alonga first data stream to an account management block 604. The block 604provides account management functions relating to the user's accountwith the ISP 232. The account management block passes data to a userpreference block 606, which retrieves user profile information and userpreferences specified by the user. Information regarding the userpreferences may be stored by the ISP 232, or downloaded from theintelligent radio 100 as needed.

Information is also passed from the process block 602 along a seconddata stream to a program management block 608. The program managementblock 608 accesses a language variety database 610 to determine whichlanguages are available, and a program variety database 612 to determinewhich types of programs are available. The program management block 608also accesses program sources such as live broadcasts 620, archivedbroadcasts 624, stored music 626, and other streaming audio sources 622.

User profile information from the user preference block 606 and programdata from the program management block 608 are provided to a programlist block 616, which constructs a list of available Web programs(broadcasts) that fit the user's preferences. The list constructed inthe block 616 is passed to the intelligent radio 100.

FIG. 6B shows the conceptual relationship between the site 602 and otherWeb sites that supply streaming audio information, such as a site 630, asite 631, and a site 632. The Internet provides the ability to transferdata between any two of the sites 602, 630-632. The user connects,through the ISP 232, to the site 602. The site 602 provides links to thesites 630-632 through the programming lists provided by the site 602. Ifthe user selects a streaming audio program from one of the sites630-632, then the site 602 provides the necessary link to the selectedsite. In some embodiments, the site 602 provides the link information tothe intelligent radio 100, and the intelligent radio 100 makes a“direct” connection to the selected site. In other embodiments, the site602 links to the selected site, receives the streaming audio data,reformats the data if desired, and then sends the streaming audio datato the intelligent radio 100.

FIG. 7 illustrates an embodiment of an intelligent radio tuner 700. Thetuner 700 is mounted in an enclosure 701 and connects to household ACpower through a power cord 104, to a network through a network cable102, and to an audio system through an audio line 702. User controls aremounted on the front of the enclosure 701 and include an on-off switch704, a command button 121, a cursor control 116, a select button 118,and a tuning control 114. The cursor control 116 provides up, down,left, and right movements of a cursor or other entity on a displaydevice 112. Also mounted on the front of the enclosure 701 is thedisplay device 112, which provides information to the user.

FIG. 8 is a block diagram of the functional elements of the intelligentradio configured as a tuner 700. The tuner 700 comprises the CentralProcessor Unit (CPU) 202 that is used to run the intelligent radiosoftware. The CPU 202 is connected to the random access memory 204, thedata storage device 210, the modem 206, and the codec 260. The datastorage device 210 may be any type of non-volatile data storage device,including, for example, a floppy disk drive, a hard disk drive, a flashmemory, a CD-ROM, a DVD-ROM, a CMOS memory with battery backup, etc. Themodem 206 is connected to a communications network 230, shown as aPublic Switched Telephone Network (PSTN). Although the communicationsnetwork 230 is shown as a PSTN network, one skilled in the art willrecognize that the network 230 may also be a cable television (CATV)network, a satellite network, or any other communications network. Themodem 206 provides an interface between the CPU 202 and thecommunications network 230 and the operational characteristics of themodem 206 are determined by the type of communications network 203.Thus, if the network 230 is a PSTN network, then a telephone modem isused; and if the network 230 is a CATV network, then a cable modem isused, etc. An Internet Service Provider (ISP) 232 provides the user witha connection from the network 230 to the Web via the Internet 234.

The CPU 202 provides data to the display device 112. The CPU 202receives user inputs from the command button 121, the tuning control114, the select button 118, and the cursor control 116. The CPU 202provides digitized audio samples to an input of a Digital-to-AnalogConverter (DAC) 220. The analog audio output of the DAC 220 is providedto the audio output 702. In a preferred embodiment, the DAC 220 is atwo-channel device, providing left and right stereo channels.

FIG. 9 is a block diagram of the functional elements of an embodiment ofan intelligent radio that provides for remote playback. FIG. 9 shows abase unit 900 that is connected to the communications network 230. Thebase unit 900 receives streaming audio from the Web and transmits theaudio information to a remote playback unit 902.

The base unit 900 is similar in most respects to the intelligent radioexcept that the amplifier 222, the loudspeakers 106 and 108, and thevolume control 110 are not located in the base unit 900, but rather arelocated in the remote playback unit 902. In the base unit, the DAC 220,the cassette device 130, the AM tuner 240, the FM tuner 242, and theexternal input 244 are connected to a transmitter 904 rather than theamplifier 222. The transmitter 904 provides a transmitted signal to areceiver 906 in the remote unit 902. The receiver 906 provides an audiooutput to the amplifier 222.

The base unit 900 receives the streaming audio information from theInternet 234 and uses a transmission carrier to retransmit the audioinformation to one or more remote units 902. The transmitter 904 and thereceiver 906 may use any form of communication for the transmissioncarrier, including radio frequency communication, infraredcommunication, ultrasonic communication, etc. In one embodiment, thetransmitter 904 may be a low power FM (Frequency Modulation) transmittercompatible with standard FM broadcast bands, such that the remoteplayback unit 902 can be a standard FM transistor radio or a stereoreceiver. In yet another embodiment, the transmitter 904 may be a lowpower AM (Amplitude Modulation) transmitter compatible with standard AMbroadcast bands, such that the remote playback unit 902 can be astandard AM transistor radio or a stereo receiver.

In other embodiments, the base unit 900 may also include an amplifier222, loudspeakers 106 and 108, and a volume control 110 such that thebase unit 900 can provide both playback of the audio information andtransmission of the audio information to the remote unit 902.

FIG. 10 is a block diagram of the functional elements of an embodimentof an intelligent radio that provides for remote access, comprising abase unit 1002 and an intelligent radio 1000. The base unit 1002comprises a transceiver 1012 coupled to a modem 1011. The modem 1011 isconnected to the communications network 230. The modem 1011 receivesdata from the ISP and provides the data to the transceiver 1012, whichthen transmits the data to a transceiver 1010 in the intelligent radio1000. The transceiver 1010 transmits data from the intelligent radio1000 to the transceiver 1012. The transceiver 1012 provides the datafrom the intelligent radio 1000 to the modem 1011, which sends the datato the ISP 232.

The intelligent radio 1000 is similar in most respects to theintelligent radio 100 shown in FIG. 2, with the addition of thetransceiver 1010. A data input/output port of the transceiver 1010 isprovided to the processor 202 and a Radio Frequency (RF) input/outputport of the transceiver 1010 is provided to an antenna. Also, in theintelligent radio 1000, the modem 206 is optional (because networkcommunications are handled by the transceiver 1010 rather than the modem206).

The transceivers 1010 and 1012 use any suitable means for communication,including, for example, optical communication, radio communication, etc.In a preferred embodiment, the transceivers 1010 and 1012 are radiotransceivers that use spread-spectrum communication techniques at afrequency of approximately 2.4 GHz. The combination of the base unit1002 and the intelligent radio 1000 provides a capability similar tothat provided by a cordless telephone. The base unit 1002 can be locatednear a network connection point (e.g., a telephone outlet), and theintelligent radio 1000 can be conveniently placed anywhere within therange of the base unit 1002. The two-way communication link between thetransceiver 1010 and the transceiver 1012 provides a cordless connectionto the network 230.

In one embodiment, the intelligent radio, as shown in FIG. 1, is anetwork-enabled audio device. FIG. 11 illustrates one embodiment of thenetwork-enabled audio device configured for use with other electronicdevices. In one embodiment, the network-enabled audio device works inconjunction with a PC. With a network connection, software on a PC canbe used to assign playlists of songs to the network-enabled audiodevice. Further, the network-enabled audio devices can be set to turn onat a certain time and play a playlist of music. In one embodiment, songsencompass a variety of audio sources including, but not limited to,audio files containing music and/or advertisements. Optionally, thenetwork-enabled audio devices can turn on through an Internet connectionas well. The front panel, including the user controls, can be disabledin order to prevent users from turning the device off when a playlist isscheduled.

In one embodiment, the network-enabled audio device records useractivity and provides that information to a server for data miningpurposes. For instance, a user's composition of a playlist includingsongs from The Beatles can be recorded by the network-enabled audiodevice and sent to a server tracking the number of users composingplaylists including songs from The Beatles. Tracking information canthen be provided to record companies interested in selling more BeatlesMP3's to gauge consumer demand. In one embodiment, a button is providedfor allowing the user to turn the logging feature on or off.

In FIG. 11, an IPAN 1100 includes an IPAN server 1104, a PC IPAN client1106, a network 1102, a device B 1108, a device A 1110, and usercontrols 1112. The PC IPAN client 1106 connects to the IPAN Server 1104through the network 1102 (such as the Internet). The Device 1110represents a network-enabled audio device, which connects at a defaulttime to the IPAN server 1104. The user can optionally change the defaulttime or can connect to the IPAN server 1104 at a desired timeindependent of the default time. The user can use the user controls 1112on the Device 1110 to bypass the default time and connect to the server1104 immediately. When the Device 1110 connects, the IPAN server 1104may have a playlist for the Device 1110. The IPAN server 1104 downloadsthe playlist to the device 1110. The IPAN server 1104 checks to see whatdevices have the audio files listed in the playlist. The IPAN server1104 maintains a list of URL's from which the device 1110 received audiofiles listed in the playlists. In one embodiment, the list of URL's isstored in a catalog. In one embodiment, the catalog also includes otherinformation such as, for example, a list of available audio playbackdevices and their settings, scheduled audio playback, and/or commandsfor system synchronization. The Device 1110 attempts to connect to theURL's listed as the location from which the songs located on theDevice's 1108 hard drive were retrieved from. If the URL's do not workand the song exists in the IPAN 1100, then the audio files aretransferred from the Device 1108 to the Device 1110 by uploading thefiles from the Device 1108 the next time the Device 1108 connects. Thenext time the Device 1110 connects, it will download the list of filesfrom the server. If the song does not exist in the IPAN, the Device 1110attempts to download the song at intervals until the user deletes thesong from the playlist or the song is added to the Device 1108. In oneembodiment, for example, an empty cone will appear beside the song inthe playlist that could not be downloaded. The user can delete the songin order to request a cease in the attempts to download, or the user canrefrain from deleting the song from the playlist in order to requestthat further attempts be made to download the song. A request forfurther attempts in downloading the song results in further iterationsof Device 1110 attempting to download the song from the broken URLfollowed by attempts to upload the song from Device 1108 when Device1108 connects.

FIGS. 12A and 12B illustrate one embodiment of a network-enabledcomponent audio device 1200. The device 1200 represents one embodimentof the intelligent radio 700.

The network-enabled audio device 1200has user controls which are mounted on the front of an enclosure 1202and include a power button 1204, a shuttle control 1214, an enter button1216, menu buttons 1212, an action button 1210, and a CD-eject button1222. On the shuttle control 1214, there is a right button 1264, a leftbutton 1260, an up button 1262, and a down button 1266 for navigatingthrough menus on the display 1230. An infrared port 1208 is mounted onthe front of the enclosure 1202 to read signals from a remote control1250. In one embodiment, the remote control includes buttons for volume,enter, navigation shuttle, action, power, CD eject, and five pre-setmenu buttons. A CD player 1220 is also mounted on the front of theenclosure 1202 to play standard audio CD's or MP3 encoded CD's.

In one embodiment, the display 1230 has a menu bar to provide the userwith options for listening to playlists, listening to the CD player, orlistening to streaming audio. The shuttle control 1214 is used to scrollthrough the selections in a playlist. Each selection is highlighted asthe shuttle control 1214 is pressed right 1264 or left 1260. When theuser makes a choice, the enter button 1216 is pressed to signify thatchoice being made. If the user chooses the playlist option, a drop downmenu is displayed in the display 1230 showing the available playlists.The user then uses the shuttle control 1214 to scroll through theplaylists by pressing the up button 1262 or the down button 1266. Oncethe user chooses an audio source with the shuttle control 1214, the usercan navigate and play the audio with the group of menu buttons 1212.

The group of menu buttons 1212 is context sensitive and will changefunction depending on the audio source. For example, in one embodiment,if the user selects the CD player 1220 as the audio source, then thefirst menu button in the group of menu buttons 1212 is used to play theCD while the second menu button is used to stop. In one embodiment, thebottom of the display 1230 changes according to the audio sourcedetermined by the user. If the user chooses to play CDs, a “play” iconappears above the first button in the group of menu buttons. In oneembodiment, if the user chooses to listen to the AM/FM radio, a scanicon appears above the first button in the group of menu buttons 1212.

In addition to allowing the user to play files, the network-enabledaudio device allows the user to play audio CD's on the CD player 1220.Further, the user can copy and encode songs off CD's in digital formats(known as “ripping”) and compose playlists with those songs and otherfiles and streaming audio.

The network-enabled audiodevice 1300 typically includes the functional elements of thenetwork-enabled audio device 1200. The network-enabled component audiodevice system 1300 includes an AM Tuner 1418, an FM tuner 1420, anamplifier 1422, and the speakers 1303. In one embodiment, thenetwork-enabled audio device 1200 does not include the AM tuner 1418,the FM tuner 1420, the amplifier 1422, or the speakers 1303. A CentralProcessing Unit (CPU) 1402 and a CPU Support Chip 1406 are used to runthe software on the network-enabled audio devices 1200 and 1300. In oneembodiment, the CPU 1402 is a StrongARM SA-1110 manufactured by Intel,and the CPU Support Chip 1406 is a StrongARM SA-1111 manufactured byIntel. The network-enabled audio device 1200 includes a display 1408, amodem 1410, a memory card 1412, a data storage device 1414, a codec1416, a CD player, a DAC 1470, a microphone 1480, a line-in port 1482,and a line out 1484. Further, the network-enabled audio device 1200includes user controls, including a shuttle control 1214, a group ofmenu buttons 1212, an enter button 1204, and an action button 1210. Thenetwork-enabled audio device 1200 connects externally to a network 1428.The network 1428 is shown as a Public Switched Telephone Network (PSTN)1428 that connects to an ISP 1429 which gives access to the Internet1102. Through the Internet 1102, a user can access the server site 1104and thereby access the server site IPAN software 1433.

In one embodiment the CPU 1402 communicates with the random accessmemory 1412, the telephone modem 1410, and the display 1408. The memory1412 can be flash memory or a combination of flash memory and othertypes of memory. The memory 1412 can be volatile or non-volatile or acombination of volatile and non-volatile. The modem 1410 is connected toa communications network 1428, shown as a PSTN 1428. In one embodiment,the modem 1410 is also connected to an HPNA network. Although thecommunications network 1428 is shown as a PSTN network, one skilled inthe art will recognize that the network 1428 can also be a cabletelevision (CATV) network, a satellite network, or any othercommunications network. In one embodiment, the network 1428 comprisesboth a Direct TV/PC satellite connection that provides information tothe network-enabled audio device at high speed (e.g., 400,000 bytes persecond or more), and a PSTN 1428 network connection so the intelligentradio can upload information back to the ISP 1429 (because many DirectTV/PC connections are only one-way). In yet another embodiment, thesatellite network is a two-way satellite network that uses the satellitefor both download and upload.

A port of the codec 1416 is provided to the CPU Support Chip 1406. Inone embodiment, the codec is a Cirrus CS4299 audio codec. The codec 1416provides analog-to-digital conversion for the microphone 1480 and forthe line in 1482, and digital-to-analog conversion for the line out1484. In some embodiments, the codec 1416 and the modem 1430 arecombined as a telephone modem.

The modem 1410 provides an interface between the CPU 1402 and thecommunications network 1428 and the operational characteristics of themodem 1410 are determined by the type of communications network 1428.Thus, if the network 1428 is a PSTN network, then a telephone modem isused; if the network 1428 is a CATV network, then a cable modem is used,etc. In a preferred embodiment, the modem 1430 is integral to thenetwork-enabled audio device. An Internet Service Provider (ISP) 1429provides the user with a connection from the communications network 1428to the Web via the Internet 1430. The server site 1104 can then beaccessed, and the server site IPAN software 1433 can be used by the userto manage audio sources and devices. Note that FIG. 14 shows functionalelements, but not necessarily hardware configurations. Thus, forexample, the modem 1410 can be implemented in software on the CPU 1402or even on the CPU Support Chip 1406. The CPU 1402 is a single computerprocessor, or multiple computer processors. In one embodiment, the CPU1402 comprises two processors, a Digital Signal Processor (DSP) and ageneral purpose microprocessor. In one embodiment, the modem 1410 isprovided in a plug-in module such that the intelligent radio can beconfigured for different types of computer networks by simply changingthe modem plug-in to suit the type of network being used.

Optionally, the microphone 1480 is connected to a second port of thecodec 1416. An analog output from the microphone 1480 is provided to thecodec 1416. A digital output from the codec 1416 is provided to the CPU1402. The microphone 1480 allows for voice commands to control thenetwork-enabled audio device. The microphone 1416 is optional. In oneembodiment, a microphone (not shown) is also placed in a wireless remoteso that voice commands can be provided from the wireless remote.Optionally, headphones can also be used.

The CPU 1402 provides data to the display device 1408. The CPU 1402receives user inputs from the shuttle control 1214, the group of menubuttons 1212, the enter button 1202, and the action button 1210.

A system bus interface interconnects the CPU 1402 to the CPU SupportChip 1406. In one embodiment, the CPU Support Chip provides digitizedaudio samples to an input of the Digital-to-Analog Converter (DAC) 1470.The analog audio output of the DAC 1470 is provided to the amplifier1422. In one embodiment, the DAC 1470 and the amplifier 1422 are eachtwo-channel devices, providing left and right stereo channels. Channeloutputs of the amplifier 1422 are provided to the speakers 1303. Thevolume control controls the gain of the amplifier 1422. In oneembodiment, the amplifier and speakers are part of an external stereosystem.

The CPU support chip 1406 is also operably connected to a CD player 1426which outputs audio to the amplifier 1422 or an external amplificationsystem. The CPU Support Chip 1406 or optionally the CPU 1402 alsomaintains software for managing the transfer of audio files from CD's tothe network-enabled audio device's hard drive.

FIG. 15 illustrates a configuration for assigning playlists and audiosources to a network-enabled audio device 1510 or other devices such asa PC 1508 from a network-enabled audio device 1520 or another device.Each network-enabled audio device 1510 has a storage space 1512 fornetwork-enabled audio device IPAN software 1526, a playlist 1528, andassociated URL's and songs within the playlist. Similarly, eachnetwork-enabled audio device 1520 has a storage space 1522 fornetwork-enabled audio device IPAN software 1526, a playlist 1528, andassociated URL's and songs within the playlist. Each client PC 1508 hasa storage space 1524 for client IPAN software 1532, a playlist 1534, andassociated URL's and songs within the playlist. The server site 1104includes server site IPAN software 1433, the playlist 1528 stored on thestorage space 1522 of device 1510, the playlist 1530 stored on thestorage space 1524 of the client PC 1508, and the playlist 1530 storedon the storage space 1522 of the device 1520. A storage space 1506 isprovided to the server site 1104 for use in uploading and downloadingaudio files when URL's are broken. Storage space 1506 for the serversite IPAN 1104 and other software programs can be stored externally orlocally at the site.

Each network enabled audio device 1510 has storage space 1512 for aplaylist 1528, which is a list of audio files and associated URL's ofwhere the audio files were retrieved from. Optionally, the associatedURL's can be archived for only file formats that are streaming audio orMP3. Multiple playlists can be stored on the storage space 1512. Inaddition to the playlist 1528, the actual audio files listed in theplaylist are also stored in the storage space 1512. The audio files canbe streaming audio, Windows Media Audio (WMA), and other audio formats.The network enabled audio device 1520 performs the same functions as thenetwork enabled audio device 1510 with the storage space 1522, theplaylist 1530, the network-enabled audio device IPAN software 1526, andsongs and associated URL's.

The PC client 1508 has a storage space 1524 for a playlist 1534 andassociated URL's and songs in the playlist. PC IPAN client software 1532is also stored on the storage space 1524. The PC client 1508 includes aweb browser (e.g., Microsoft Explorer, Netscape Navigator, etc.), anIPAN plug-in to the web browser, and an IPAN active tray softwaremodule.

The IPAN plug-in opens as soon as the web browser is opened. The IPANplug-in affects the handling of links to MP3 files, streaming audio, andany other audio file type designated. Whenever a user selects, saves, oropens a file in the web browser, the IPAN plug-in intercepts the normalprocessing of the web browser and will check to see if the file is anaudio file. If the file is an audio file, the IPAN plug-in will allowthe user to download the audio file to the IPAN 1100 now or to schedulethe file for download at a later time. In either case, the URL can beadded to the playlist. Further, the IPAN plug-in will periodicallyconnect to the server site IPAN software 1433 to receive softwareupgrades or to upload updates of the audio files present on the clientPC 1433.

The web browser can be used to connect to the server site 1104 andprovide access to the server site IPAN software 1433. The IPAN activetray software module runs in the background when the PC client 1508 isturned on. Without the web browser being opened, the IPAN active traysoftware module can play audio files in playlists.

At the server site 1104, the user can access the server site IPANsoftware 1433 through a network connection to the server site IPAN 1104and from the server site IPAN software 1433 the user can assignplaylists to different devices such as the network-enabled audio device1510, the network-enabled audio device 1520, or the client PC 1508. Theuser composes the playlists from the server site IPAN software 1433, buttypically only stores the title of the song and the URL from which thesong came. The playlists stored throughout the IPAN 1100 are also storedin the server site IPAN 1433. The user then has a master list of whereall playlists are located. When the device 1510 connects to the serversite IPAN 1104, a playlist is assigned to it. Within the playlist, theURL's indicate the location from which the audio files associated withthe song titles in the playlist can be downloaded. The network-enabledaudio device 1510 then proceeds to download the song from the given sitespecified by the URL to the disk space 1512 on the device 1510. If thesite at the URL is not working, the server site IPAN software 1433 willupload the playlist from the disk space 1522 of another device 1520 thenext time the second device 1520 connects to the network. The next timethe original device 1510 calls in, it will download the playlist fromthe server site 1104.

Further, the server downloads software upgrades, if necessary, when thedevice accesses the IPAN 1433. For example, if the disk space in adevice that was supposed to have a playlist was accidentally erased,then the server site 1104 provides the URL's for sites to download thelost playlists. In addition, the server site 1104 downloads any othersoftware used to enhance the communications between the server and thedevice. Software can also be downloaded to be used by the CPU 1402 orthe Support Chip CPU 1406.

In one embodiment, there is no server site 1104. The PC IPAN clientsoftware 1532 stores the playlists that are located throughout the IPAN1100. Through a network connection, the PC IPAN client software assignsplaylists to devices 1510 and 1520.

FIG. 16 illustrates the connection steps used when the user first setsup the network-enabled audio device. A user begins at process block 1601by connecting the speakers and radio antennas to the back of the unit.The user also takes other preparatory measures such as plugging in theAC power cord and connecting a phone cable to a telephone jack. At thenext process block 1602, the user can choose to begin listening topreloaded music without setting up any of the software by pressing thepower button 1204 on the machine and pressing the “Listen Now/SetupLater” button on the first screen. The user can thus listen to preloadedmusic before even setting up the software for the network-enabled audiodevice. The process then advances to the next process block 1603 wherethe user can scroll through the playlists of preloaded music by usingthe shuttle control 1214 and the enter button 1216. At the next processblock 1605, the user begins to set up the network-enabled audio device1200 by inserting a setup CD into the CD player 1220. The processadvances to process block 1606 where the user returns to the firstscreen and selects “Setup Now” in order to begin loading the PC IPANclient software 1532 on the network-enabled audio device 1200.

If the user designates a portable device, the devicewhich the portable device will be connected to is entered in the field1774 to provide the IPAN with information about how to access theportable device. The download time is entered in the field 1775 toprovide the IPAN with the time when the user would like the device toautomatically download. The default time is set to early morning (e.g.between midnight and 5 a.m.) because that is the time when the leastamount of people are on the telephone and the Internet. The downloadduration is entered into the field 1776 to provide a maximum time limitfor download duration if desired. The default is unlimited, but the usercan set a maximum time so that if the download is not finished withinthe time limit, the device signs off. Before signing off, the currenttask will be completed. In other words, if the maximum time is exceededin the middle of downloading the third song in a download of ten songs,the task of downloading the third song will be completed. The downloadwill continue where it left off upon initiation of the next downloadcommand. In the previous example, the download will continue at thefourth song. Finally, the server site IPAN software 1433 willautomatically install downloaded files in a designated folder unless theuser specifies a different location in the field 1778.

FIGS. 18A through 18H illustrate the use of the display 1800 on thenetwork-enabled audio device. In FIG. 18A, the screen display 1802includes a “Radio” menu item 1804, a “Playlist” menu item 1806, a“Favorites” menu item 1808, a “Jukebox” menu item 1810, a “CD” menu item1812, and an “Internet Radio” menu item 1814. Residing in the lowerportion of the display 1800, the menu buttons 1821-1825 are in the groupof menu buttons 1212 and are provided to correspond to icons 1841-1845residing in the lower portion of the display 1800. Each one of the icons1841-1845 represents a different function to be performed with respectto a selected audio source.

The user selects items from the screen display 1802 by using the shuttlecontrol 1214 and the enter button 1216. For example, to select the “CD”audio source, the user presses right shuttle control 1264 until the “CD”menu item is highlighted. The user then presses the enter button 1216.Once an audio source is selected, context sensitive icons 1841-1845appear above the corresponding menu buttons 1821-1825. Depending on thechosen audio source, the icons 1841-1845 represent different functions.

FIG. 18B illustrates the screen display 1802 when the audio source is anAM/FM radio, such as the AM/FM “Radio” menu item 1804. The menu item1804 is highlighted to indicate that the AM/FM “Radio” audio source hasbeen chosen. The menu buttons 1821-1825 change context to correspond toicons that represent functions related to the audio source selected.Because the AM/FM “Radio” audio source was selected, the menu buttons1821-1825 change context to correspond to the icons for an AM/FM tuner.The icons 1841-1845 shown as, respectively, a play icon 1841corresponding to a play function 1830, a scan next icon 1842corresponding to a scan next function 1832, a scan previous icon 1843corresponding to a scan next function 1834, a radio presets icon 1844corresponding to a radio presets function 1836, and a stop icon 1845corresponding to a stop function 1838. As further illustrated in FIG.18C, if the menu button 1823 corresponding to the icon 1844 representingthe radio presets function 1836 is pressed, the menu buttons 1821-1825change context to correspond to icons 1841-1845 which represent thechoice of preset stations with each of the functions 1870-1874corresponding to a different radio station. In one embodiment, the radiosource menu option 1804 is omitted.

FIG. 18D shows the screen display 1802 after the user has selected thePlaylist menu item 1806. The menu buttons 1821-1825 are used to selectfrom various playlist icons 1841-1845. The icons 1841-1845 shown as,respectively, a play icon 1841 corresponding to a play function 1875, arecord icon 1842 corresponding to a record function 1876, an export icon1843 corresponding to an export function 1877, and back to previous menuicon 1845 corresponding to a back to previous menu function 1878. Theshuttle control 1214 and the enter button 1216 are used to select a songfrom the playlist in order to play. The record function 1876 will recorda playlist to the network-enabled audio device's storage device 1510.The export mode downloads the playlist to a portable player. After asong is chosen from a playlist in FIG. 18D, FIG. 18E shows the menubuttons 1821 and 1822 changing context to correspond to icons 1840 and1841. The icons 1841 and 1842 are shown as, respectively, a delete icon1841 corresponding to a delete function 1848 and a back to previous menuicon 1850 corresponding to a back to previous menu function 1850.

FIG. 18F illustrates the Jukebox audio source 1810, which provides alisting of all the audio files stored on the hard drive 1512 of thenetwork enabled audio device 1510 by Title, Artist, Album or Genre. Themenu buttons 1821 and 1822 change contexts to correspond go icons 1840and 1841. The icons 1841 and 1842 are shown as, respectively, a playicon 1849 corresponding to a play function 1849 and a back to previousmenu icon 1851 corresponding to a back to previous menu function 1851.

FIG. 18G illustrates the CD audio source 1812 being selected. The menubuttons 1821-1823 change context to correspond to icons 1841-1843. Theicons 1841-1843 are shown as, respectively, a Name CD icon 1841corresponding to a Name CD function 1852, a Record CD icon 1842corresponding to a Record CD function 1854, and a back to previous menuicon 1843 corresponding to a back to previous menu function 1856. TheRecord CD function 1854 can be used to copy tracks from a CD to the harddrive 1512 for future use in playlists. The Name CD function 1852 isused to retrieve a title name for a track and other information via theInternet from a CD database site after the Record CD function 1854 hasbeen used to copy the CD to the hard drive. In one embodiment, an onlinedatabase is checked via the Internet.

In FIG. 18H, when the CD player is being played, menu buttons 1821-1825change context to correspond to icons 1841-1844. The icons 1841-1845 areshown as, respectively, a previous track icon 1841 corresponding to aprevious track function 1892, a pause icon 1842 corresponding to a pausefunction 1894, a next track icon 1843 corresponding to a next trackfunction 1896, and a stop icon 1844 corresponding to a stop playfunction 1898.

FIG. 19A is a flowchart that illustrates an audio query process 1900 ofthe IPAN 1100. The audio query process 1900 begins at start block 1940where the PC IPAN client software 1532 is opened. In one embodiment, aportion of the PC IPAN client software 1532 is part of the “active tray”so that when a user turns the PC 1508 on, the PC IPAN client software1532 is opened. Further, a portion of the PC IPAN client software 1532is part of the IPAN plug-in so that when an Internet or other networkconnection is established, the PC IPAN client software 1532 runs in thebackground to query whether to add an audio file found on the Internetto the server site IPAN 1104. The process advances to a process block1942 where the user finds a desired audio file as addressed by a URL.The user can search the Internet for audio without having to access theweb site associated with the server site 1502. In a decision block 1944,the user is asked, through a menu, if the file is to be downloaded. Ifthe process advances to a process block 1948, the user has decided todownload the file now and the playlist is added to the IPAN 1100. At aprocess block 1950, the file has been downloaded and is available forplaying. If the user decides “NO” (i.e. to download the file at a latertime or at the default time) the process advances to a process block1946 to download the file at that default or more convenient time. Theprocess then advances to a process block 1948 when the file is added tothe IPAN 1100. The web site associated with the server site 1104 doesnot have to be opened. The PC IPAN client software 1532 will downloadthe software to the hard drive of the PC 1508 and connect to the website associated with the server site 1508 to upload the audio files. Atthe final process block 1950, the audio files will be available forplaying.

FIG. 19B is a flowchart 1900 that begins at start block 1902 andillustrates the assignment of playlists to devices. The process advancesfrom the start block 1902 to a process block 1904 where the user logsinto the server site IPAN 1433. The process advances to the next processblock 1908 where the user assigns a playlist to a first device 1510. Inone embodiment, the playlist is stored in an SQL database and accessedvia active server pages. After the active server pages access the SQLdatabase, the playlist is downloaded to the first device 1510. Theprocess then advances to a decision block 1908 where the process checksto see if all the songs in the playlist are stored in the first device'shard drive 1512. If all the songs in the playlist are already on thefirst device 1510, the songs on device 1510 are catalogued as beingpresent. If songs need to be downloaded, the server site IPAN 1433 formsa list of remaining songs. In the next process block 1910, the serversite IPAN 1433 compares the list of remaining songs to its records ofthe songs present on the device 1520 to see if the device 1520 has someof the necessary songs to complete the playlist formation. If the seconddevice 1520 does have some of the remaining songs, the URLs of thosesongs, which are stored on the Server site IPAN, are provided to thefirst device 1510. The remaining songs which the second device 1520 doesnot have are deleted from the list of remaining songs and do not becomepart of the playlist. In the next process block 1914, the first device1510 will download the songs from the URLs provided to it by server siteIPAN 1433. The first device 1510 downloads all of the remaining songsneeded for the playlist from the second device's 1520 URL's, but if allthe songs are not on the second device's 1520 playlist, the first device1510 will either get them from another device or in the worst casecompose a playlist from only the songs that could be retrieved.

In the decision block 1916, the process determines if any URLs arebroken. If A is unable to download the files from the URLs, the serversite IPAN 1433 will upload the files to the server site in process block1920, store the files in the interim, and download the files to thefirst device 1510 in process block 1922 the next time the first device1510 calls in. For instance, the first device 1510 can be located on theeast coast, and the second device 1520 can be located on the west coast.The first device 1510 may be assigned a playlist that is stored on thedisk drive 1522 of the second device 1520. When the first deviceconnects (e.g., at 2 a.m.) to the server site IPAN 1433, the firstdevice will receive the URL's for the location where the second device1520 downloaded the audio files and now the first device 1510 candownload the audio files. If the URLs are broken, the first device 1510will disconnect. When the second device 1520 calls in three hours laterat 2 a.m. Pacific Time, the server site IPAN 1433 will upload the audiofiles to the server site 1104 and store the files on the disk space1506. When the first device 1510 connects at 2 a.m. the followingevening, the audio files will be ready to download from the server site1104 to the first device 1510. The audio files will finally be stored onthe disk space 1512.

At process block 1922, the songs that are present on the device 1510'sstorage space, the songs that have been downloaded from URL's to thedevice 1510, and the songs that have been uploaded to the device 1520are catalogued in the IPAN 1100. In one embodiment, the songs arecatalogued in the IPAN 1100 at the time that they are found. Forinstance, the songs that are on the device 1510's hard drive found atthe process block 1908 can be catalogued in the IPAN 1100 at that timerather than at process block 1922. Further, the songs downloaded fromURL's can be catalogued at process block 1916 or decision block 1916.Finally, the songs uploaded from the device 1520 can be catalogued atthe time of uploading at process block 1918 or at the time ofdownloading at process block 1920. Optionally, delays in cataloguing canbe used. In one embodiment, for example, the uploaded songs and thedownloaded songs are all catalogued at process block 1920 whereas thesongs present on the device 1510's storage space are catalogued at thedecision block 1908.

FIG. 19C is a flowchart 1980 that illustrates another embodiment of theprocess of flowchart 1900. In one embodiment, the flowchart 1980 hasprocess and decision blocks that handle an assignment of a playlist thatincludes songs not present on the device 1510. The process advances fromthe start block 1902 through 1908 in the same fashion as the process inflowchart 1900. In contrast to the process in flowchart 1900, theprocess then advances to decision block 1990 rather than 1910. Atdecision block 1990, if songs need to be downloaded, the server siteIPAN 1433 checks its records to see if the device 1520 has all thenecessary songs on the list of remaining songs to complete the playlistformation. If the device 1520 has none or some but not all of thenecessary songs, the process advances to a process block 1950. At theprocess block 1950, the necessary songs that are not present on thedevice 1520 are catalogued in the new playlist with empty cone iconsnext to those songs. Optionally, the icon can be a symbol other than anempty cone. The playlist is not yet completely formed and will haveadditions of songs that are present on the device 1520 at a later pointin the process. The process then advances to a process block 1952 anddeletes songs that the device 1520 does not have from the list ofremaining songs. The process then advances to decision block 1954 todetermine if the list of remaining songs is empty. If the list ofremaining songs is empty, then the process advances to process block1922 where the songs present on the device 1510's storage space 1512 arecatalogued in addition to the missing songs that are catalogued. In oneembodiment, cataloguing does not include multiple entries for songsdetermined to be present at an earlier time. For instance, if a song ispresent on a device and is catalogued once as being present on thedevice, a multiple entry for the song being present on the device willnot be made at a subsequent iteration of the process. If the list ofremaining songs is not empty, the process advances to the process block1912. At the process block 1912, the process in the flowchart 1980proceeds in the same fashion as the process in flowchart 1900 until theprocess advances to the process block 1922. After all the songs(including the missing songs) are catalogued at the process block 1922,the process advances to the process block 1960 where the list ofremaining songs is deleted. At the process block 1962, if the playlistdoes not contain any songs with an empty cone icon, the playlist iscomplete and the process advances to the end process block 1924. If theplaylist contains any songs with an empty cone icon, the processadvances to the decision block 1964 to allow the user to delete themissing songs. If the user deletes the missing songs, the playlist iscomplete, and the process advances to the end process block 1924. If theuser decides not to delete the missing songs, a new list of remainingsongs is created consisting of the missing songs not deleted by theuser. The process then advances to the decision block 1990.

At the decision block 1990, if the device 1520 initially had all theremaining songs on the playlist, the process 1980 proceeds in the samefashion as the process 1900. In one embodiment, if the process advancedfrom the process block 1966 rather than 1908, the missing songs havebeen added to the storage space 1522 of the device 1520 so that theplaylist can now be complete. The process advances through iterationsuntil all the songs present on the playlist are present on the storagespace 1512 of the device 1510 or until the user deletes songs fromplaylist so that no missing songs are present. In one embodiment, theprocess advances from the process block 1966 to the decision block 1908in order to check whether the missing songs have been added to thestorage space 1512 of the device 1510 or the storage space 1522 of thedevice 1520 so that the playlist can now be complete.

In one embodiment, the IPAN 1100 includes a network connection so thatthe first device 1510 and the second device 1520 can have audio filesdownloaded from the first device 1510 to the second device 1520 almostinstantaneously after the assignment of an audio file to the device1510. For example, in a home network, the device 1510 does not need toconnect to the Internet and can retrieve the necessary file through thenetwork connection.

FIGS. 20A-20F illustrate the use of the action button 1210 on thenetwork-enabled audio devices 1200 or 1300. FIG. 20A illustrates thescreen display 1802 before the action button 1210 has been pressed. Inone embodiment, the action button 1210 can be pressed when an audiosource (e.g. an audio source in MP3 file format) with an unidentifiedartist is playing. Optionally, the action button 1210 can be pressedwhen an audio source in MP3 file format with an identified artist isplaying. Optionally, the action button 1210 can be pressed for audiosources such as, for example, streaming audio, files in WMA file format,CDs, etc. The menu buttons 1821-1825 represent the functions that can beperformed on the given audio source before the action button 1210 ispressed. For an MP3 file, for example, the menu buttons 1821-1825correspond to a “pause” function, a “next” function, a “previous”function, an “add favorites” function, and a “stop” function. After theaction button 1210 is pressed, the menu buttons 1821-1825 change contextto perform functions that provide additional information on the givenaudio source and artist. Further, after the action button 1210 ispressed, the artist will no longer be shown as “unknown” because theaudio source will be uploaded to a server for analysis to determine theidentification of the artist. The server will download the identity ofthe artist in addition to other information concerning the audio source.

FIG. 20B illustrates the screen display 1802 after the action button1210 has been pressed. The “unknown” artist in FIG. 20A has beendetermined to be “Moby,” and the unidentified MP3 file has beenidentified as “Porcelain.” The menu buttons 1821-1825 correspond to menuitems that provide information on, or related to, the audio source. Atitle menu 2002 is provided to indicate the location in the directory ofaction button options that the user has chosen. If the user is at thebeginning of the action button directory structure, the screen display1802 illustrates the text “action” in the title menu 2002.

The menu buttons 1821-1825 correspond to the menu items “news,” “music,”“tour,” “offers,” and “done.” By choosing the menu item “news,”information will be presented to the user of current events regardingthe artist and/or the given audio source. For instance, the “news”function can display Billboard top 40 information, clothing linesintroduced by the artist, new albums, etc. The menu button 1822corresponding to the “music” menu item provides the user access to otheraudio sources from a given artist. The menu button 1823 corresponding tothe “tour” menu item allows the user to get up-to-date information ontours that the artist is going on. The menu 1824 corresponds to the“offers” menu item which allows the user to receive information onmerchandise, promotional items, etc. for the given artist. The menubutton 1825 corresponding to the “done” menu item allows a user to turnoff the action button 1210.

FIG. 20C illustrates the screen display 1802 after the menu item “music”has been chosen. The menu path 2204 lists “action” to indicate to theuser that the menu title “music” 2202 was a menu item chosen from themenu items illustrated in the screen shot denoted by the menu title“action.” The menu buttons 1821-1825 correspond to the menu items“albums,” “similar,” “samples,” “back,” and “done.” If the user selectsthe “albums” menu item the user will be able to view a list of otheralbums by the artist of the audio source. In one embodiment, the serverdownloads the albums listing when the action button 1210 is pressed forthe first time. Optionally, the server downloads additional informationafter the user selects one of the menu buttons 1821-1825. When the userpresses the menu button 1822, the “similar” menu item is chosen and alisting of albums that are from a genre of music similar to that of theaudio source or from artists that are in some way similar to the artistof the audio source is presented. If the “similar” menu item isperformed on Moby and “Porcelain,” a list of techno songs from Mobyand/or techno songs from other artists can be presented. If the userpresses the menu button 1823 corresponding to the “samples” menu item,audio samples from the artist will be presented. If the user presses themenu button 1824 corresponding to the “back” menu item, the locationillustrated in the menu title is returned to. If the user presses themenu button 1825 corresponding to the “done” menu item, the actionbutton 1210 is turned off.

FIG. 20D illustrates the screen display 1802 after the menu item“albums” has been chosen. The menu path 2204 lists “action/music” toindicate to the user that the menu title “albums” 2202 was a menu itemchosen from the menu items illustrated in the screen shot denoted by themenu title “music.” The menu buttons 1821-1824 correspond to differentalbums for the given artist. FIG. 20D illustrates four of Moby's albums:“Moby,” “Ambience,” “Everything is Wrong,” and “Animal Rights.” The menubutton 1825 corresponds to the “done” function which allows the user toturn the action button 1210 off.

FIG. 20E illustrates the screen display 1802 after the menu item“Ambient” is chosen on the screen display 1802 illustrated in FIG. 20D.The menu path 2204 action/music/albums shows that “Ambient” was chosenfrom the menu title “albums” 2202. The menu item “buy” is chosen topurchase the album “Ambient.” The menu item “download” is chosen todownload the “Ambient” album. The menu item “listen” is pressed to allowthe user to listen to the album. The menu item “back” allows the user toaccess the previous menu title. To reach the screen shot with the menutitle “albums” from the menu title “Ambient,” the user chooses the“back” menu item. The user can turn the action button off by pressingthe “done” menu item.

FIG. 20F illustrates the screen display 1802 after the user determinesto buy the album illustrated in FIG. 20E. The menu pathaction/music/albums/buy indicates that the user chose the “buy” menuitem in FIG. 20E. The title menu 2202 “complete” is used at the end ofthe transaction. The menu item “buy” can be chosen to allow the user tocomplete the transaction. To reach the screen shot with the menu title“Ambient” from the menu title “Complete,” the user chooses the “back”menu item. The menu button 1825 corresponds to the menu item “done”which allows the user to turn the action button 1210 off.

In FIG. 20B, if the menu item “news” is chosen by the user, thesubsequent screen will display the menu path “action,” the menu title“news,” and the menu items: “listen,” “read,” “log to myactions,”“back,” “done.” If the user chooses the menu item “read,” a subsequentscreen displays the menu path “action/news,” the menu title “read,” andthe menu items “log to myactions,” “back,” and “done.” If the userchooses the menu item “log to myactions,” information about a particularartist or a particular audio source will be stored in a log for futurereference. The displayed menu path will be “action/news/to myactions,”the menu title will be “complete,” and the menu items will be “back” and“done.”

If instead of reading the news, the user would like to listen to the“news,” the “listen” menu item can be chosen in the screen displayingthe “action” menu path and the “news” menu title. The next screen willdisplay the “action/news” menu path and the “listen” menu title. Thescreen will also alert the user as to the status of the retrieval of thenews. The menu items include “log to myactions,” “back” and “done.”

In FIG. 20C, the user can choose the menu item “samples” so that thenext screen displays the menu path “action/music,” the menu title“samples,” and the menu items which include different audio sourcesamples. After the user chooses a sample from the menu items of samples,a screen displays the menu path “action/music/samples,” the title menu“Ambient,” and the menu items “buy,” “download,” “listen,” “back,” and“done.” If the user chooses to select the “buy” menu item, the nextscreen displays the menu path “action/music/samples/buy,” the menu title“complete,” and the menu items “back,” and “done.”
